The Summer I Turned Pretty season 3 book plot: Who does Belly end up with?

Like seasons 1 and 2, The Summer I Turned Pretty season 3 will be based on the books. The third book, We'll Always Have Summer, is the final instalment of the series and has plenty of material for the show to adapt. The book wraps up Belly's storyline, with plenty more drama when it comes to her relationships with Conrad and Jeremiah.

It also takes place over multiple years so fans thought that Jenny Han mights split the events of the book over two seasons. However, it's now been confirmed that season 3 is the show's final season. In other words, the show will likely end how the books end.
